ITo (din-7mm it mag concern:

Be it known that -I, ALEXANDER IIoovEN and \VILLIAM IIENRY ADLE, ofNorristowmin the county of Montgomery andState of Pennsylvania, haveinvented certain new and useful Improvements in a Machine for Rollin gIron or other metals and we dohcreby declare that the i'ollowing'is afull, clear, and exact description thereof, which will enable othersskilled in the art to which it appcrtains to make and use thesame,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

.l igure 1 is a top orplan view of the machine.

- by three rolls throughout the process of rollin g, all as hereinaftermore fully set forth.

-In the drawings, A marks the bed-plate of the machine, and A the framein which the operative parts are'supported. In this frame are adiustablyfixed the journal-boxcsof the rolls B U I) E F G ll I J K, whosejournals I) c d of g h '6 k are seen in end view in Fig. 2, supported intheir respective boxes, which are fixed in the desired positionbythescrews S S, &c. Guides L M N O are introduced between the rolls, asshownin Fig. 3, for the purpose. of directing the barot' metal in theproper path in its passage through the machine.

he train of gears byavh'ieh the rolls are driven is hung in the oppositeside of the frame, and the journals of the shafts are supported andadjusted by screws S in the same manner as the journals of the rolls.They are coupled to the shafts of the rolls by means of the sleeves 11'', Q, Q, &e., provided with bars I), and with the strips 0 and bands(1 for keeping the sleeves in position when the shafts of the rolls andgears are coupled.- The opening through the sleeves isangular, and-cori;e--

spends in shape and size with the herb and with the inner ends of thejournals of the rolls and driving-gears, on whielrthe sleeves are,respectively, placed. This arrangement .is

clearly shown at Q Q, Figs: 1, 4, and 5, the

sleeve Q being placed onthe' inner end of the journal of roll 0 andsleeve Q on the inner end of the journal of shaft 0'. The bar Z) entersboth sleeves and connects them, and the strips 0, bound to the bar I) bythe straps 01', hold the sleeves apart and on the journals which theyrespectively receive.

To u-neouple the journals of rolls 0 and C, or any other pair in theseries, it is only necessarytoieiuovc the strips 0 aud-bringthe sleevestogether, .when they, with the bar b, can be removed from between theends of the journals to which they had'be'en applied.

The rolls B C D E F G H I J K are arranged relatively to each other inthe manner shown in Fig. 3, roll 0 being nearer to.D thanto B, roll Ebeing nearer toF than to 1), and so on through:

out the series, J and K, the final pair, being separated by a distanceequal to the final thickness of the rolled metal. The gears on shafts BO D 1*) F G H I J K are so timed as to give increased speed over itspredecessor to each successive roll from Bto K so as to produce acombined drawingand compressing action -upon the metal. c

B Fig. 3, marks the bar of metal passin g through the machine. Itreeeivesits first re-' duction between rolls 1 and O, the next between Cand D, then between 1) and E, E and F, F and G, G and H, H and I, I andJ, and finally between J and K, each group of three rolls throughout theseries efi'ectiug two -reductions, as clearly shown. v

The guides L M N 0 guide the bar in the proper path through the machine,preventing it from following around either of the rolls which areoperating upon it. a

We are aware of the existence of a patent-,-

dated August 12, 1873, No. 141,701, -to E. H. Davies, for a machine forrolling sheet metal, in which is shown a series of pairs of rol'lers,

with gradually-increasing pressure, and hav iug intermediate rollersarranged between the pairs of rollers and resting upon the bottoui'.

ries;

' i We claimrollers of the adjoining" pairs. Such construction we do notclaim; but u 1. In a, machine for rolling metal, the combination, in themanner described and shown,

* of a series of rollers arranged relatively to each 0ther,'so that eachroller shall be nearer the roller which follows than to the one whichprecedes it, and so that two reductions of the metal are eflected bythree rollers at one operation, all as specified.
